Among these, body fat calipers are a widely available option, but can be catchy to use to get accurate results.

1

Enlist professional person aid to get the most accurate results. Experience counts when using skinfold calipers because the accuracy of the test depends on precision of measurement. "Competent" examiners have executed l – 100 tests in controlled enquiry settings.^[three] Experienced examiners are more likely to have measurements at the aforementioned point over time, which volition give y'all the well-nigh accurate results for tracking your progress.
two

Ask a friend to aid. If a professional is not administering your test, go along in mind that collecting measurements from sure points, such every bit your back, may exist difficult — if not impossible — on your own.

Learn how calipers work. Body fat calipers do not measure out trunk fat percentage directly. They are used to administer the "pinch test," which takes measurements of skinfolds from iii to ten points on the body.^[4] That information is and then plugged into a formula to compute your torso fat percentage. The accurateness of skinfold calipers for measuring body fatty percentage depends on both the feel of the person using the calipers and the formula used to compute the results.
4
Select a sensible formula. There are over 100 equations used to calculate trunk fat percentage from a compression test. Each is specific to groups of people according to characteristics such as age, gender, race, and fitness level, which touch where bodies tend to store adipose fat. Plugging in the same data to several different equations tin can return results that vary past several percentage points.^[v]
- Common equations include Jackson & Pollock, Parrillo, and Navy Tape.
- To cull a formula that makes sense for you, work with a fettle professional and utilize information technology every bit a criterion of your progress. Or, forgo the formula completely and only keep track of the skinfold measurements.^[half-dozen]
- Many body fat calculators are available online, making it piece of cake to summate the results of a pinch test with a few or several measurements.^[vii]
5
Track your progress. At the get-go of a fitness regimen to reduce your trunk fatty per centum, it is useful to get a baseline measurement. Go along this information in a log (personal training journals and fitness apps are practiced options) along with your practise routine (e.grand., mileage walked, weightlifting sets) over time.
- Recommended ranges for a healthy per centum of trunk fat differ co-ordinate to gender, age, and fitness level. Women with more than 32% of body fat and men with more than 26% of torso fatty are considered obese.^[eight]

- You may desire to invest in high-quality calipers, which volition be more expensive. Inexpensive calipers may not exert the advisable amount of constant pressure necessary to provide adequate tension control and reliable results. Some highly recommended calipers include Harpenden Skinfold Calipers, Lafayette Skinfold Calipers, Lange Calipers, Slim Guide Skinfold Calipers, and Accu-Measure Body Fat Calipers.^[9]

1

Choose a test. Compression tests mensurate skinfolds at 3, four, seven, and even ten points on the body. Taking measurements from more points does not ensure accuracy of the body fat percentage adding. That depends on the precision used when taking the measurements and the formula used to calculate body fat.
two
Place the points at which you lot'll take measurements. The central is to exist consistent with the exact locations likewise every bit pinch-type (vertical vs. horizontal). In general, the correct side of the body on a continuing subject area is used when obtaining measurements. Mutual areas to measure skinfolds include:^[10]
- Triceps — Have the subject bend the elbow to 90 degrees and marking the point midway between the top of the shoulder and elbow.^[xi] Then, measure a vertical fold (with the calipers at a 90 degree angle) at that midway signal with the arm hanging naturally at the subject's side.
- Biceps — With the arm extended naturally at the discipline's side, accept a vertical fold at the front of the arm, halfway between the shoulder and the crook of the elbow.^[12]
- Subscapular — Measurements of the subscapular surface area should be taken as a diagonal fold (calipers held at a 45 degree angle) beyond the back, just below the shoulder blade.^[13]
- Thigh — Take a vertical fold on the standing leg, midway betwixt the kneecap and the crease where the thigh meets the hip.
- Iliac crest — Have the subject hold their right arm across the body. Employ a horizontal pinch to take this measurement right in a higher place the hip bone on the side of the torso.^[14]
- Abdominal — A measurement in the abdominal surface area should be a vertical fold one inch to right of umbilicus.
- Calf — With the human foot resting on a chair or platform at approximately xc degrees, take the measurement as a vertical fold on the inside of the calf at the indicate with the largest circumference.^[fifteen]
- Chest — Measure the pectoral region past taking a diagonal fold midway between the nipple and upper function of the pectoral muscle at the armpit.^[16]
- Axilla — The axilla surface area is on the side of the upper chest. A measurement here should be taken every bit a vertical fold directly under the center of the armpit and perpendicular to the nipple.
- Supraspinale — A measurement of the supraspinale area should be a diagonal fold at the intersection of a vertical line betwixt the spinal (front part of iliac crest, the protrusion of the hip bone) and front part of the armpit) and a horizontal line at the acme of the iliac crest.^[17] This region is also called the suprailiac, in some measurement systems.
three
Compression a fold of pare and pull. Making a "C" with your left thumb and index finger, grab as big of a skinfold as yous can until it hurts, then pull outwards.^[18] Be sure that you pinch the same exact amount of peel at the aforementioned exact location for repeat measurements.
- Information technology is important that you do not exclude any "pinchable" peel nor include whatever underlying musculus.
4
Agree the pair of calipers using your correct hand with the thumb on the upper arm and index finger on the lower arm. Place the jaw ends over the skinfold while continuing to pinch the skinfold with your left paw. Using your right pollex, printing down where indicated on the caliper until you feel a slight click. This sound represents the correct measurement as the caliper jaws automatically stop at the width of your skinfold. Repeat this step three times for each landmark to ensure reliability. If the measurements differ (they should only differ by 1 – 2 mm^[nineteen]), obtain and record the boilerplate of the iii measurements.
- Exist certain to measure the centre of the skinfold betwixt your fingers.
five

Tape measurements on paper. Be sure to record the boilerplate of all three measurements in an organized way to avoid confusion during adding. Its best to use a notebook and save all measurements equally a log and so you lot may compare them as time goes on.

Enter the average measurements for each bespeak into the formula you're using. Afterward calculating your event, tape information technology in your fitness journal or app.
